Actividad de adiestramiento en cardioversión eléctrica en la Unidad de Electrocardiología del CCR-ASCARDIO

Cardiovascular diseases are one of the main causes of mortality worldwide being heart rhythm disorders one of the most frequent cardiac pathologies. Electrical cardioversion is a technique that allows the transfer of electrons to the myocardium in order to interrupt arrhythmias with reentry mechanisms allowing the sinus node to take control of heart rate. The appropriate selection of cases susceptible to electrical cardioversion as well as experience on this technique increases the success rate and decreases the number of failed attempts. The Electrocardiology unit of the CCR-ASCARDIO has experience in the study and treatment of arrhythmias. In this article we present the development of a training program on electrical cardioversion, essential tool for cardiologists, with the aim to increase the correct use of this technique in order to prevent complications due to heart rhythm disorders.Las enfermedades cardiovasculares son una de las principales causas de mortalidad siendo los trastornos del ritmo cardiaco una de las patologías cardiacas más frecuentes. La cardioversión eléctrica es una técnica a través de la cual se realiza una transferencia de electrones al miocardio con la finalidad de interrumpir arritmias con mecanismos de reentrada permitiendo al nodo sinusal retomar el control de la frecuencia cardiaca. La correcta selección de los casos susceptibles de cardioversión eléctrica y experiencia en cardioversión aumenta la tasa de éxito y disminuye el número de choques fallidos. En el CCR- ASCARDIO, la Unidad de Electrocardiología cuenta con experiencia en el estudio y tratamiento de arritmias. En este artículo se presenta la elaboración de un programa de adiestramiento en la técnica de cardioversión eléctrica siendo esta terapia una herramienta imprescindible para la práctica clínica del cardiólogo, facilitando la prevención de complicaciones derivadas de los trastornos del ritmo cardiaco

Transmission of ‘Candidatus Liberibacter solanacearum’ by Bactericera trigonica Hodkinson to vegetable hosts

The bacterium ‘Candidatus Liberibacter solanacearum’ is a recent plant pathogen of several crops in Solanaceae and Apiaceae and is associated with economically important diseases. The bacterium is a carrot seed borne pathogen that can also be transmitted from potato mother tubers and by psyllid vectors. The psyllid Bactericera trigonica Hodkinson was described carrying CaLso associated with vegetative disorders in carrot and celery crops in Spain and its competence to transmit this phloem-limited bacterium among vegetables is currently being investigated. Here electrical penetration graphs showed that B. trigonica fed in the phloem of carrot and celery and probed the phloem in potato, but not in tomato plants. The bacterium was efficiently transmitted to carrot and celery plants when either single B. trigonica or groups of ten fed on these species. An inoculation access period of 24 hours was sufficient for a single B. trigonica to transmit the bacterium to carrot (67.8%), celery (21.1%) and eventually to potato and tomato (6.0%). Higher transmission rates were obtained with 10 individuals on celery (100%), carrot (80%), potato (10%) and tomato (10%). Bactericera trigonica laid eggs, and the hatched nymphs develop into adult on carrot and celery, but not on potato and tomato. CaLso was detected in 20% of the eggs laid by females carrying the bacterium. The results confirmed that B. trigonica is a vector of the bacterium to carrot and celery, and it is discussed the potential role of this psyllid in the transmission of the pathogen to potato and tomato plants

Supraspinal shaping of adaptive transitions in the state of functional connectivity between segmentally distributed dorsal horn neuronal populations in response to nociception and antinociception

In the anesthetized cat the correlation between the ongoing cord dorsum potentials(CDPs) recorded from different lumbar spinal segments has a non-random structure,suggesting relatively stable patterns of functional connectivity between the dorsalhorn neuronal ensembles involved in the generation of these potentials. During thenociception induced by the intradermic injection of capsaicin, the patterns of segmentalcorrelation between the spontaneous CDPs acquire other non-random configurationsthat are temporarily reversed to their pre-capsaicin state by the systemic injectionof lidocaine, a procedure known to decrease the manifestation of neuropathic painin both animals and humans. We have now extended these studies and utilizedmachine learning for the automatic extraction and selection of particular classes ofCDPs according to their shapes and amplitudes. By using a Markovian analysis, wedisclosed the transitions between the different kinds of CDPs induced by capsaicinand lidocaine and constructed a global model based on the changes in the behaviorof the CDPs generated along the whole set of lumbar segments. This allowed theidentification of the different states of functional connectivity within the whole ensembleof dorsal horn neurones attained during nociception and their transitory reversal bysystemic administration of lidocaine in preparations with the intact neuroaxis and afterspinalization. The present observations provide additional information on the stateof self-organized criticality that leads to the adaptive behavior of the dorsal hornneuronal networks during nociception and antinociception both shaped by supraspinaldescending influencesPeer ReviewedPostprint (published version

O CONTEXTO PÓS-DEMARCATÓRIO: QUANDO SE TRATA DE REDEFINIR O CONTROLE SOCIAL SOBRE OS RECURSOS NATURAIS E BENS CULTURAIS

O artigo apresenta formulações que se desdobram da síntese teórica para a reorganização social de grupos étnicos elaboradas pelo antropólogo João Pacheco de Oliveira, em especial quando atrelada à conquista de garantias fundiárias. A intenção, neste momento, foi avolumar a discussão desse lugar teórico estabelecido pelo supracitado autor para aprofundar a ideia da redefinição do controle social sobre os recursos ambientais. A expectativa é que, ao explorar tais concepções, seja possível contribuir para os estudos voltados à compreensão de movimentos identitários socioespaciais reivindicatórios, gerando aportes para interpretações do momento pós-demarcatório, dialogando com o que é denominado atualmente de gestão ambiental e territorial em terras indígenas. Neste ensaio, formulou-se a ideia da redefinição do controle social sobre os recursos naturais e bens culturais como fenômeno relevante nas interpretações de processos de reorganização social de repercussão territorial de grupos sociais e étnicos

Reengagement of HIV-infected children lost to follow-up after active mobile phone tracing in a rural area of Mozambique

Introduction: Retention in care and reengagement of lost to follow-up (LTFU) patients are priority challenges in pediatric HIV care. We aimed to assess whether a telephone-call active tracing program facilitated reengagement in care (RIC) in the Manhiça District Hospital, Mozambique. Methods: Telephone tracing of LTFU children was performed from July 2016 to March 2017. Both ART (antiretroviral treatment) and preART patients were included in this study. LTFU was defined as not attending the clinic for ≥120 days after last attended visit. Reengagement was determined 3 months after an attempt to contact. Results: A total of 144 children initially identified as LTFU entered the active tracing program and 37 were reached by means of telephone tracing. RIC was 57% (95% CI, 39–72%) among children who could be reached versus 18% (95% CI, 11–26%) of those who could not be reached (p = 0.001). Conclusion: Telephone tracing could be an effective tool for facilitating reengagement in pediatric HIV care. However, the difficulty of reaching patients is an obstacle that can undermine the program

The challenge of environmental samples for PCR detection of phytopathogenic bacteria: a case study of citrus huanglongbing disease

Huanglongbing (HLB) is the most devastating citrus disease and is associated with three bacterial species of the genus ‘Candidatus Liberibacter’ transmitted by insect vectors. The early detection of HLB is based on PCR methods, and it is one of the cornerstones for preventing incursion into disease-free countries. However, the detection of phytopathogenic bacteria with PCR-based methods is problematic in surveys that include a variety of samples of different origins. Here, we first report the proportion of amplifications obtained by two standardized real-time PCR methods for the diagnosis of HLB in various environmental samples that include plants, psyllid vectors, and parasitic wasps of the psyllids. The results of 4915 samples showed that 9.3% of them were amplified by the first rapid screening test and only 0.3% by the more specific tests. Most of the amplifications were associated with parasitic wasps. We designed the primers external to the target regions of both real-time PCR protocols to determine if amplifications belonged to one of three ‘Ca. Liberibacter’ species associated with HLB. The bioinformatic analysis of the sequences obtained with these primers revealed that all these amplifications came from the presence of other prokaryotic organisms in the samples. The primers developed in this study overcome the problem of undesired amplification in environmental samples. Thus, they could be used in future survey protocols to prevent the eradication of negative trees and the generation of unjustified alarms

Avifauna de los Pueblos Santos de la Sierra Madre del Sur de Guerrero: análisis de la riqueza y recambio taxonómico entre tipos de vegetación

The Sierra Madre del Sur is a region biologically important for its high levels of richness and endemism. In the last two decades, the pressure on their natural resources has increased, which threatens its biodiversity. In this study, we analyzed the bird biodiversity of the Pueblos Santos in the Sierra Madre del Sur, state of Guerrero and the species turnover was evaluated among the main vegetation types present: cloud forest, pine-oak forest, oak-pine forest, semideciduous forest and tropical dry forest. The field work was performed in 11 months distributed from 2006 to 2012. The species records were obtained through visual and auditory methods and capture of specimens.Birds were categorized by their seasonality, endemism, and risk category. A total of 136 species were recorded corresponding to 34 families and 15 orders. Cloud forest had the higher species richness (70 species), followed by oak-pine forest (59), tropical dry forest (46) and semideciduous forest (24). The greatest number of resident species (64 species) was found in the cloud forest and the highest number of migratory species (12 species) was registered in tropical dry forest. A total of 15 endemic species to Mexico and four quasi-endemic species were registered, of which the tropical dry forest had the highest number of species. Nine threatened species and nine species under special protection were registered. The cloud forest had the highest number of species at risk (16 species). There was a greater similarity in the composition of birds between the cloud forest and pine-oak forest, while the tropical dry forest presented the greatest difference in relation to the other vegetation types. In terms of the richness-area relationship, the bird biodiversity and the richness of endemism in the Pueblos Santos are high. This avifauna, as well as the vegetation types that they occupy in the region, will require of management and conservation strategies to ensure their long-term permanence.La Sierra Madre del Sur es una región biológicamente importante por sus altos niveles de riqueza y endemismo. En las últimas dos décadas ha aumentado la presión sobre sus recursos naturales, lo que pone en riesgo su biodiversidad. En este estudio se analizó la biodiversidad de las aves de los Pueblos Santos de la Sierra Madre del Sur en el estado de Guerrero y se evaluó el recambio de especies entre los principales tipos de vegetación presentes: bosque mesófilo de montaña, bosque de pino-encino, bosque de encino-pino, selva mediana subcaducifolia y selva baja caducifolia. El trabajo de campo se realizó en 11 meses repartidos del 2006 al 2012. La información de las especies se obtuvo mediante registros visuales, auditivos y captura de ejemplares. Las aves se categorizaron por su estatus estacional, endemismo y categoría de riesgo. Se registró un total de 136 especies de aves agrupadas en 34 familias y 15 órdenes. El bosque mesófilo de montaña presentó la mayor riqueza de especies (70 especies), seguido del bosque de encino-pino (59), selva baja caducifolia (54), bosque de pino-encino (46) y selva mediana subcaducifolia (24). En el bosque mesófilo de montaña se encontró el mayor número de especies residentes (64 especies) y en la selva baja caducifolia el mayor número de migratorias (12 especies). Se registraron 15 especies endémicas a México y cuatro cuasiendémicas, de las cuales la selva baja caducifolia presentó el mayor número de especies. Se registraron nueve especies amenazadas y nueve en protección especial. El bosque mesófilo de montaña presentó el mayor número de especies en riesgo (16 especies). Existió una mayor similitud en la composición de aves entre el bosque mesófilo de montaña y el bosque de pino-encino, mientras que la selva baja caducifolia presentó la mayor diferencia con relación a los otros tipos de vegetación. En términos de la relación riqueza-área, la biodiversidad de aves y la riqueza de endemismos en los Pueblos Santos es alta. Esta avifauna, así como los tipos de vegetación que ocupan en la región requerirán de estrategias de manejo y conservación para asegurar su permanencia a largo plazo
